PROTOCOL WITH DOSE OPTIMISATION FOR ATTENUATION CORRECTION AND LOCATION DETERMINATION ON HYBRID SCANNERS Russian patent published in 2017 - IPC A61B6/03 

Abstract RU 2634622 C2

FIELD: medicine.

SUBSTANCE: hybrid imaging system comprises the first imaging system configured to obtain low resolution anatomical data for the first field of view of the anatomical structure, the second imaging system configured to obtain functional data for the first field of view of the anatomical structure, a reconstructing processor configured to reconstruct an image with an adjusted attenuation from functional data, based on the attenuation data. In response to the adjusted attenuation image, the first imaging system or another imaging system obtains high resolution anatomical data of one or more parts of the first field of view. Low resolution anatomical data is obtained in the first field of view, and high resolution anatomical data is obtained in one or more of the second observation fields, and each second field of view is smaller than the first field of view. High resolution anatomical data is obtained using a CT scanner using a high dose of radiation, and low resolution data are obtained using a dose that is substantially lower than the high dose of radiation. The imaging method is implemented through a hybrid visualization system. In the second method embodiment, a functional image covering the first field of view of the patient is generated, the functional image is analyzed for areas of interest that includes, in response to one or more areas of interest identification in the functional image, one or more anatomical high resolution images covering one or more of the second survey fields are generated. Each second field of view covers at least one area of interest and is less than and is contained in the first field of view (106), and method termination in response to identified absence of areas of interest, without generating an anatomical high resolution image.

EFFECT: use of inventions allows to expand the arsenal of tools for multimodal visualization.
